首先从指定路径读取图像,将图像大小更改为224*224,并将图片范围从0-255改为0-1: from PIL import Image image= Image.open(path) image=image.resize((224,224)) x_data= x_data.astype(numpy.float32) x_data= numpy.multiply(x_data,1.0/255.0) ## scale to [0,1] from [0,255] 由于此数据集中...
Caltech 256数据集是加利福尼亚理工学院收集整理的数据集,该数据集选自Google Image数据集,并手工去除了不符合其类别的图片。在该数据集中,图片被分为256类,每个类别的图片超过80张。为什么要用Densenet121模型?本项目使用在PyTorch框架下搭建的神经网络来完成图片分类的任务。由于网络输出的类别数量很大,简单的网络模型...
